Seated Back Twist

Instructions

1
Sit on the floor with knees bent and feet flat on the ground, positioned close to your buttocks. Lean back slightly so your torso is at approximately 45 degrees from the floor with a neutral spine.
2
Place both hands behind your head with fingers interlaced, keeping elbows wide. Ensure your neck remains neutral and do not pull on your head. Engage your core by drawing your navel toward your spine.
3
Slowly lower your torso backward by extending through the spine and hip flexors, allowing your back to lengthen and decompress. Keep your feet planted and maintain tension in the abdominals throughout the lowering phase.
4
Drive through your abdominals to pull your torso upward and forward, returning to the starting seated position. Exhale as you contract and flex the spine, bringing your ribcage toward your pelvis. Maintain control and avoid using momentum.

Overview

Athletic trainers and bodybuilding coaches frequently recommend the Seated Back Twist because it challenges the Rectus Abdominis through a dynamic range of motion. By relying on Body weight, it reinforces proper movement patterns and builds robust strength in the Waist region.

Benefits

  • Promotes balanced muscular development by effectively recruiting the Rectus Abdominis and associated synergists.
  • Acts as a highly scalable Strength, Stretching movement, perfect for both beginners and elite athletes.
  • Reduces the likelihood of Waist injuries by reinforcing connective tissue strength.

Common Mistakes

  • Using excessive momentum to swing the Body weight rather than controlling the eccentric phase.
  • Failing to achieve a full range of motion, which drastically limits Rectus Abdominis engagement.
  • Shrugging the shoulders or compensating with secondary muscles rather than isolating the Rectus Abdominis.
  • Losing core tension, leading to poor spinal alignment and reduced power output.

Pro Tips

Control the eccentric (lowering) phase of the Seated Back Twist for 3-4 seconds to drastically increase time under tension.

Muscle Anatomy

The primary driver is the Rectus Abdominis. However, the movement also recruits Iliopsoas, Rectus Femoris, Sartorius, Obliques to maintain control of the Body weight.
